Hi Howzat,
I missed your original thread but, have you tried a mix of;
1 part Detol (True Detol only)
1 part Tap Water
and a small amount of baby oil (sufficient to make the stuff stick to your skin).
Put the mix into a spray bottle and give it a good shake then spray on the exposed skin. It beats the clappers out of anything else commercial or homemade. It also gives an anti-bacterial layer to prevent infection of any bites that you do get.
